BAYONET GUN-SOCKET THEREFOR.

Specification of Letters Patent. Patented Sept, 23 1919 Application filed Iune 16,1919. Seria1No.804,533.

- useful Improvements in Bayonet and Gun- Sockets Therefor, of which the following is a specification.

The primary object of the present invention is to provide a. bayonet attachment for guns wherein the bayonet is normally carried within a housing formed at the muzzle end of the gun barrel with automatic means. for projecting and limiting the outward movement of the'bayonet to its operative position when it is desired to use the gun during a charge.

Another object of the invention is to provide a gun having a bayonet normally housed .therein and wherein the bayonet, when certain retaining devices are released, is permitted during a fencing operation automatically to move forward to the limitof its movement and be rigidly supported its full operative position.

With the above and other objects in view, the invention consists in the combination and arrangement of parts herein fully described in connection with the accompanying drawing, in which like reference characters indicate similar parts throughout. the several views. I

In the drawing, I

Figure 1 is a side elevational view of the muzzle end of a gun constructed in accordance with the present invention with a'portion of the muzzle end thereof broken. away and with a bayonet in operative position.

therein,

Fig. 2 is a View similar to Fig. 1 with the I bayonet in retracted position and with the bayonet housing shown in section,

Fig. 3 is a bottom plan'view of the construction shown in Fig. 1, i

Fig. 4 is a cross sectional View taken on line IVIV of Fig. 3 showing the retaining shoe in the bayonet housing forengaging the bayonet while in projected position, Fig. 5 is a cross sectional view taken on line V-V of Fig. 4,

Fig. 6 is a sectional view of a portion of i integral therewith, the bayonet casing terminating at the extreme muzzle end of the barrel and being of a length to completely house the bayonet 10.

' The interior of the bayonet casing 9 is 11 of the bayonet is of similar formation and relatively long so that the-bayonet will slide within the casing and be prevented from.- relatlve rotary movement and retained centrally positioned at all times. The inner open end of the bayonet housing is closed by a screw plug 12 having secured to theinner face thereof an expansion coil spring 13 that is engaged and compressed by the stock 11 of the bayonet 10 when the bayonet is I in its completely retracted'position as shown in Fig; 2. A

With the bayonet positioned in the housing 9, the same is engaged at the pointed end 14 thereof by a shoe 15, the inner end of the shoe 15 being provided with a recess 16 into which the pointed end of the bayonet is received and protected thereby. Theishoe rectangular in cross section. and the stock" 15 is positioned in the enlarged outeF -Tiind 17 of the bayonet casing 9 and is carried by a pair of pins 18 that freely project through openings provided in the adjacent wall of the outer end 17 with expansion coil the spring 13 to assist the outwardly sliding movement of the bayonet. pulling pres sure upon the handle 20 is released and the springs 19 surrounding the rods between the shoe will ride upon the outwardly moving end 16 engaging the'pointed end 14 of the bayonet. When it is desired to have the bayonet 1O operatively positionedrelative to the muzzle 8, it is only necessary to laterally shift the shoe 15 in the enlarged housing section 17 by pulling upon the handle 20 which will free the outer end of the bayonet from the shoe socket and by the expansion of the spring 31 assisted by a throwing or charging movement of the gun, the bayonet will be thrown forwardly with the shoe riding thereover until such time'as the shoe registers with the socket in the bayonet stock 11 whereupon the springs 19 will exert their force to move the shoe into said socket and rigidly position the bayonet in operative position for immediate use.

from the socket 21 and compressing the bayonet against the tension of the spring 13, one of the main functions of the spring 13 being to provide a cushion seat for said bayonet and further to protect the point 1& thereof, the-spring 13 and shoe l5 coiiperating to hold the bayonet in the casing against The bayonet is re placed in the casing 9 for removing the shoe What I claim as new is 1. In combination with a gun barrel, a bayonet slidably supported thereby and means for limiting the outwardly sliding 'movement of said bayonet, said means moving transversely of said gun barrel for engagement with the forward end of said bayonet when in inoperative position.

' 2. In combination with a gun barrel, a bayonet slidably supported thereby, means for limiting the outwardly sliding movement of said bayonet, said means moving transversely of said gun barrel for engagement with the forward end of said bayonet when in inoperative position, and resilient means associated with the first named means for holding the same in operative position.

3. A device of the class described com prising a gun barrel, a housing carried thereby, a bayonet slidably mounted within said housing, and having a socket in the side thereof adjacent its inner end, a tensioned shoe adapted to move transversely of the outer end of said socket and normally in engagement With the outer end of said bayonet, the said shoe adapted to be received in the bayonet socket when the bayonet is projected from said casing.

4. A device of the class described comprising a gun barrel, a housing carried thereby, a bayonet slidably mounted within said housing and having a socket adjacent its inner end, a shoe adapted to be moved transversely of the outer end of the casing, rods carried by said shoe freely extending through the casing wall, an operating handle for said shoesecured thereto and extending through said casing wall, and expansion coil springs surrounding said rods and handle, the shoe adapted to be received in said bayonet socket when said bayonet is projected from said casing and to limit the outward sliding movement of said bayonet.

' In testimony whereof I affix my signature.
